London Metropolitan Archives, London, England

This charter, written in Old English, survives in the original and has been in the city of London’s keeping continuously since 1067. It is endorsed with one contemporary word, now illegible, and 'Carta regis Willelmi de libertatibus' in a 12th-century hand. The charter is vellum and has two slits, the larger one used as a seal-tongue and the other as a tie. The seal impression, which is detached and imperfect, is the earliest surviving example from William’s reign.
